trols and when either open or closed; one in which the construction shuts off access -of the fluid or water from the screw stem at all times so that corrosion of the threads is prevented; a valve of improved construction whereby either end of the shell or casing can be connected tothe supply without interfering with the correct and satisfactory `operation 'of the valve; one whose resistance, as compared with the usual types of globe valve is very small; and a valve whose" pacln'ng or washers can be readily removed and others substituted therefor.

- My improved valve, which -is adapted for use with air, gas or liquid, embodies a novel annular and cross seat and sloping parts in the shell or casing leading to said cross seat, whereby the supply may belet into either end of the valve shell or casing.

The invention also consists of a valve of improved construction adapted Afor removably holding packing on both of itsfaces and for itsswivel connection to the valve stem; further,y in a valve -carryingpacking on its opposite lfaces and coperating with a seat on the valve bonnet and also with. the fluid control seat, together rwith guiding means interposed between the valve and the valve body and a swiveled connection between the stem and the valve, whereby the valve is packed or sealed when both open and closed. t

The invention is susceptible of modification and the disclosures herein are to be considered as illustrative,rather than restrictive, of the scopeof the invention.

One-embodiment of the invention is ,shown in the accompanying drawings, in which- Figure 1 is a sectional view in perspective; Fig. 2, a top perspective of the valve;.F1g. 3, a bottom perspective thereof; and Fig. 4,

a top perspective the stem.

rThe valve body 1 has lan annular ridge constituting a valve-Seat 2 and a cross-piece or seat member 3 whose upper edge or face hes in the same plane with. the upper edge or face of the seat 2, and to which the bottom of the body 1 slopes, preferably on a curve at 4, the seat member 3 constituting the ridge or top of the sloping portions 4. By virtue of .this construction, either end of the body 1 of the gland that swivels cou ling upthe valve.

he uprightportion of the body is provided with guide ribs 5, preferably arranged at mnety degrees apart. The valve bonnet 6 is adapted to be secured to the body by removable bolts7 and has a stutling box 8, as usual, but it differs from the usual type of bonnet in that there is provided an annular seat 9` which is spaced apart from the the same and projects downwardly therein.

The valve 10 is provided with projections, ears or lugs 11 which straddle the ribs 5 and snugly yet easily receive them, thus providing for a guiding ofthe valve in its reciprocations. In the upper face of the valve 10 is an annular packing receiving seat or channel 12 containing a gasket or vpacking ring 13, against which the seat 9 bearswhen the valve is completely open, thus shutting oilI the admission of the fluid to the interior of the bonnet and to the valve stem 14. The

annular ridge 15 which results from the employment 'of the ,channel 12 surrounds and overlaps the seat 9 when the valve is completely open and thus enhances the sealing action at this point.

The bottom face of the valve 10 has a concavity as at 16 and receives a packing disk or washer 17. A gland 18 bears against the upperface of the valve 10 and overlaps the packing13 and holds fit in the channel 12. The hub of this gland holds the head 19 of the stem 14, thus providing a swivel connectionbetween `the stem 14 and the valve' 10. Bolts 20 pass throughholes in the valve 10fand through the washer 17 and gland 18,

thereby constituting a common means for holding the packing o n both sides of the valve 10 and for securing the gland` 18. By the employment of these two bolts, I accom- .i i may be coupledto the supply pipeand .consequeutly care does notl have to be taken in f .inner face of the valve body where it enters soy push the triple object of securing the two packings and swiveling the stem to the valve.

The valve stein threads 21.- Y c When the valve is down,.the washer or has the Vusual screwseat 17 bears against the annular'seat 2mv and I turned. When thus closed,

The pressure of the straight cross-piece against the washer 17 prevents any buckling of the central portion thereof in additionto seal-- lng communication between the inlet .and outlet of the v valve casing, while the annu. lar seat -2 prevents passage of the Huid upwardly, when the valve is-closed. As'the'` gas, air or water, is p1'evented .run having access tothescrew-threads 21? and they are thus prevented from corroding.- On'remov# the bonnet andavalve `and stem can be taken 4out andkjthe,"bolts- 20v quickly removed to v renew the seatv Al'Z- or lthe packing or seat 13;
